Strange Vibrations

[fordel]

ok....


so after i went for a nice little drive yesterday along a nice smooth graded dirt road, i now have a strange vibration from underneath my car.

it happens when you engage the clutch for the first time, happened from cold start this morning as well.

also notice it about 3000rpm when it revs to that

i am thinking its the exhaust heat shield or something like that that .. i hope.... any other ideas what it may be ?
